Phil Steitz resolved MATH-1066.
-------------------------------
Resolution: Fixed
Revised patch committed in f80f577748c0dbde45d24654247a82a7121d456c and
540aa2e7ed7c0c0add1daad7fb548e156435e0a2
Changes to the patch:
* Eliminated some needless constants from the Fortran translator
* Made variables that could be final, final
* Simplified some logic
* Improved javadoc
* Externalized strings
* Made exceptions more precise
* Added tests for exceptions
* Made the results class and more complete method public
I did not change variable names, as keeping the same names will make
troubleshooting problems / comparing results with the original Fortran code
easier.
Thanks for the patch!

> According to the Wish List, special functions are a priority item to be added
> to ACM. As Bessel functions (http://en.wikipedia.org/wiki/Bessel_function)
> are listed by name, I have translated some Fortran code from Netlib --
> specifically, http://www.netlib.org/specfun/rjbesl -- for Bessel functions of
> the first kind.
